ADJUSTER FOE PNEUMATIC MECHANOTHERAPEUTIC RECEIVERS.

Application filed April 28, 1914.

To all 11- 7mm it may concern:

Be it known that I, HOLLAN N. D. PARKER, citizen of the United States, residing at l Vashington, in the District of Columbia, have invented certain new and useful Improvements in Adjusters for Pneumatic Mechanotherapeutic Receivers; and I do hereby declare the following to be .a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same- This invention relates to improvements in pneumatic mechano-therapeutic apparatus devices for the treatment of disease by enforced blood circulation as distinguished from the administration of drugs.

As is well known, apparatus for vacuum treatment requires the use of a receiver for application to the part to be subjected to the vacuum action, air being exhausted from the receiver, and thus promoting circulation of the blood and vital fluids in the part to'which the receiver is applied. Where the receiver is superimposed on a comparatively flat surface of the body, or a portion thereof to which the mouth of the receiver will readily conform, the exhausting of the air therefrom will affix the receiver sufficiently tight to maintain the vacuum conditions within the receiver, but when a limb is to be inserted within the receiver, it is difficult to obtain the proper atmospheric conditions between the surface of the limb and the mouth of the receiver contiguous thereto for maintenance of the vacuum. It is, therefore, the main and primary object of the present invention to provide simple and efiicient means through the medium of which a tight joint may be established between the limb and the receiver without inducing tension on the muscles above the portion of the limb inclosed within the receiver, whereby to enable the vacuum conditions to be readily and expeditiously obtained, and also maintained during the period of treatment.

A further object of the invention is the provision of means for the purpose stated capable of application to limbs of varying sizes, so that a single receiver is adapted to thus preclude the necessity for a plurality of receivers for. this purpose.

WVith the foregoingobjects in view, and others which will appear as the nature'of the improvements is better understood, the

Specification of Letters Patent.

Patented Sept. 18, 1917.

Serial No. 835,007.

invention consists substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, wherein is illustrated what is believed to be a preferred embodiment of the invention Figure 1 is a side elevation of a pneumatic mechano-therapeutic receiver equipped w th an adjuster constructed in accordance with the present invention, a hand being illustrated as positioned in the receiver for treatment.

Fig. 2 is a longitudinal sectional view of the receiver and the associated adjuster, the same being removed from the hand.

'Fig. 3 is a perspective view of the adjuster, the members thereof being open to illustrate the position assumed thereby when applying the adjuster to a limb.

Fig. 4 is a detail sectional view through one of the hinges of the adjuster members.

Fig. 5 is a perspective view of the mouth of the receiver, illustrating the means for joining the adjuster to the receiver.

Fig. 6 is a detail sectional view taken through the meeting ends of the adjuster members when the latter are in closed position.

Referring in detail to the accompanying drawings, the numeral 10 designates a pneumatic mechano-therapeutic receiver. This is in the usual form of a cylindrical body closed at one end, as at 11, and open at the other end, and said body is provided with a nipple 12 to which may be applied the usual connection from an exhausting device, such as a pump, for removing the air from the interior of the receiver. The mouth of the receiver 10 is surrounded by an inclined flange 13, and at the base of said flange-the body of the receiver is slightly enlarged to provide an annular shoulder 14, for a purpose to be presently stated.

Associated with the receiver 10 is a conical adjuster 15. This adjuster comprises a pair of complemental reversely-arranged members 16, each of which is substantially semi-frusto-conical,the contiguous edges of said members through the major portion of their length, and when the members are in closed position as illustrated inFig. 2, lying against each other.' These edges, however, adjacent to the basal portions of the memhere 16, are cut away or flared, as at 17.,

Lana

whereby to permit the members to swing open with respect to each other, as illustrated in Fig. 3, and said members, at points adjacent to said cut-away portions, are hingedly connected by links 18, said links being arranged at the inner faces of said members, and being connected thereto by rivets 19, or their equivalent. The members 16 are thus enabled to swing with respect to each other, to permit opening and closing of the adjuster when placing the same upon, and removing, it'froin, a hand or leg which it is desired to subject to treatment in the receiver '10.

At the smaller end of the adjuster 15, which constitutes the mouth thereof, each of the members 16 is provided with a curled bead 20,.the ends of the bead of one member registering with the ends of the bead of the other member, and within one of said beads 20 is disposed a wire 21, the ends of said wire projecting beyond the ends of the bead which receives the same, and thus in a ,Josition to enter the open ends of the bead 20 of the other member 16. The projecting ends of the wire 21, therefore, constitute guides, and by the entry of the same within the tubular head of the opposite member 16, the proper positioning of the mouth ends of the members 16, when thesame are closed upon each other, is insured.

For the purpose of strengthening the members 16 they are provided with annular corrugations or beads 22, any number of which may be employed.

In order to properly connect the adjuster 15 to the mouth of the receiver 10, the basal end of each of the members 16 is provided with an inwardlyextending stud 23, said studs being arranged opposite to each other, and these studs are adapted to engage bayonet. slots 24, which are disposed at opposite points, and reversely arranged with respect to each other, inthe inclined flange 13 ot the recelver 10. The circumferential portions of the slots 24 are inclined, as clearly seen in Figs 2 and 5, the purpose of this being to impart to the studs 23 a drawing or wedging action when the adjuster 15 is assembled upon the receiver 10. It will, therefore, be seen that, when the adjuster 15 is applied to the receiver 10, the'incline'd portions of the slots 24: effect a tight engagement of the basal portion of; the ad juster on the flange 13, bringing it into engagement with the shoulder 1%, and in this connect on it will also be noted that the inclination of said flange 13 is slightly greater than the inclination of the members 16, when they are closed, the flange 13 therebycausing the mouth ends of said members 16 to bem ed towa d ch the to he m i m ext nt n. ar w th fl nge 13 bein more in ined he b sal po t ns of th m m r 16,. the actiqn cf e flan e 13,

when the adjuster is applied thereto, is essentially a wedgmg actlon to close to the fullest extent the mouth ends of said members.

In the use of the hereindescri bed adjuster, the members thereof are spaced apart, as

illustrated in Fig. 3. This opens the mouth end of the adjuster to permit introduction of the limb with ease and facility, and when the adjuster has been applied to the limb, the mouth ends of the members 16 are pressed toward each other, the guide wire 21 entering the tubular head on the opposite section. The receiver 10 is then applied to the adjuster, the studs 23 entering the bayonet slots 24, and by causing relative rotation between the receiver 10 and the adjuster 15, the studs 23 are wedged into the circumferential portions of the slots 24. This causes a locking engagement between'the adjuster and the receiver, confining the limb to be treated within the adjuster and i the 'receiver; A bandage 25, in the form of an elastic strip, preferably rubber, is now wrapped in spiral convolutions' about the limb, adjuster and the adjacent portion of the receiver 10, as illustrated in Fig, 1, thereby. sealing the joints, and with the nipple 12 connected tothe exhausting device, it will be obvious that when the air is removed from the receiver the limb confined in the latter will be subjected to the desired treatment,

By reasonof'the construction of the adjuster 15, it will be readily seen that the same may be adapted to limbs of different sizes, mouth ends of the members 16 conforming tothese sizes within the range of tl'ltillTOPQllllig and closing inovement,so that a single receiver will sufiice for appli cation to varying'sizes of limbs. "The necessit) f r. a plurality of receivers is thus overcome.

Having thus described the invention, what isclaimed as-new, and desired to be secured by Letters Patent, is:
